STREET-CLEANING MACHINE.

Specification of Letters Patent.

Patented July 3, 1917.

, Application filed September 13, 1916. Serial No. 119,907.

To all whom it may concern Be it known that THOMAS F. HAeEn'rY, deceased, late a citizen of the United States of America, residing at New York, inthe county of New Yorkand State of New York, did invent new and useful Improvements in Street-Cleaning Machines, of which the following is a specification.

This invention relates to street cleaning machines, and it has particular reference to that class in which loosening and removal. of the dirt from street surface is effected by means of a scraper.

The present invention has for its object to produce a machine of simple and improved construction in whichthe frame that carries the scraper also supports a receptacle for the dirt, and means for transferring the dirt from the scraper'to the receptacle. A further object of the invention is to produce a simple and improved machine in which the frame that supports the scraper alsocarries a receptacle to receive the dirt,

a movably supported scoop for transferring the dirt from the scraper to the receptacle and a specially constructed revoluble element for throwing the dirt from the scraper into the scoop, the latter being. so supported that it may be retracted with respectto the revoluble element. so as to clear the same when it is tilted to transfer its contents to the receptacle.

Further objectsof the invention are to simplify and improve the construction and arrangement of the detailed parts of the device. j i a With these and other endsin view which will readily appear as the natureof the invention is 'better understood, the same consists in the improved construction. and novel arrangement, and combination of parts which will-be hereinafter fully described and particularly pointedout in the claims. In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural detailstherein exhibited, but that changes. alterations and modifications within thescope of the claims maybe resorted towhen desired.

In the drawingr- '1 Figure 1 is a vertical longitudinal sectional view of a machine constructed in accordance with the invention, taken on the line 11 in Fig. 2.

Fig. 2 is a top plan view.

Fig. 3 is a detail view in elevation of a portion of the frame showing also the dirt receptacleand a portion of the scoop.

Fig. 4 is a detail plan view showing a portion of the scraper and related parts.

Fig. 5 is a fragmentary detail view of one of the bearings for the pushing element shaft.

Corresponding parts in' the several figures are denoted by like characters of reference.

The wheel supported side members 15 of the frame are provided with spindles 16 on which the grounded wheels 17 are supported for rotation. At the forward ends of the frame members 15 the frame bars .18 are pivotally. supported by pivot members 19, said forward ends'of the frame members 15 being preferably slightly upturned, as clearly seen in Figs. 1 and 3. The rearward ends of the frame members 15 have upturned brackets 20 which are connected together by a cross bar 21 on which the frame bars .18 are normally supported,said frame bars being, however, free to rock slightly about the pivot members 19, as indicated in dotted lines in Fig. 3, said rocking movement being limited by stop members, such as hooks 22 which by engagement with thevprojecting ends of the cross bar 21 will limit the rocking movement of the frame bars 18. The frame bars 18 at their upper rear ends are connected together by a handle bar 23; the lower front ends of the frame bars 18 are equipped with angular brackets 24 on which the scraper25 is supported and secured by fastening members, such as rivets 26. The

scraper 25 is preferably made of such a length that it will project terminally be yond the side members of the frame, thus D whichis revoluble therewith; Said dirt core 31 consisting of aflat piece of sheet metal upon which bristles or fibrous material, indicated at 32, is secured by wire stitching33, the purpose, however, being simply to show a flat flexible or yieldable revoluble dirt pushing element, the free edgesof which, as the shaft 28 revolves, will push the dirt rearwardly over the scraper 25, there being no intention for said ele ment to contact with the surface of the street or to act as a dirt gathering sweeper.

Bearing blocks 34 for the shaft28. may be I mounted for vertical adjustment 011 the brackets 27 as indicated in Fig. 5, for the purpose of enabling the dirt pushing element to be vertically adjusted so as to compensate for wear.

A dirt receptacle 35 of ample capacity is mounted on the cross bar 21 bymeans of ears or lugs 36 pivotally engaging said'cr'oss bar, said receptacle being capable of swinging in an upward and rearward direction so as to discharge its contents over the rear edge thereof into a can or other receptacle placed in'the street or into some other con venient receptacle, not shown. The receptacle 35 may be supported in dirt'receiving position by a cross bar 37 connecting the frame members 15 or in any other convenient manner. The frame members 15 are connectedtogether near their front ends by a cross bar 38 on which are pivoted links 39 with which the top edge of a scoop 40 is pivotally connected, said scoop having a bottom member, 41 which in practice is supported on the brackets 24 beneath the rear ward portion of the scraper 2 5, saidscraper being supported in a slightly tilted position, so as to enable the. frontportion of the bottom member 41 .of the scoop to be pro jected therebeneath, as clearly seen in Fig. 1 will also be readily seen that the manner of supporting the scoop 40 onthe links 39 will permitthe scoop to be retracted from beneath the scraper so as to clear not-only the scraper, but also the flat dirt pushing element when it is desired to tilt the scoop forthepurp'ose-of discharging its contents into the receptacle 35, as indicated in dotted lines'in' Fig. F1. vFor the purpose of convenien' c'e in manipulating .the. scoop" is prov'ided witha handle42 p In the operation of this device the scoop is adjusted fto th e. position shown fin full lines" inggri' 1,- and the means is then latter with respect to the ground, thereby rendering its operation more effective and preventing it from sliding freely over the accumulated caked substance, and this will be accomplished, owing to the pivotal connection ofthe frame bars 18 with'the frame members 15, without raising the wheels 17 from the ground and consequently without interrupting the operation of the revoluble element D. When a quantity of dirt has been gathered in the scoop; 40, the operator by grasping the handle 42 may retract the scoop with respect to the scraper and the revoluble element until the upper edge of the scoop abuts on the front edge of the re 'ceptacle 35; the scoop may then be tilted, as .seen in dotted lines in Fig. 1, to discharge its contents into the receptacle, after which it is restored to its initial position. The contents of the receptacle 35 maybe discharged at stated intervals whenever desired by'tilt'ing said receptacle about the axis. of the cross bar 21'. p

Having thus described the invention, what is claimed as new, is K ,1. In a machine of the class described, a pair of wheel supported frame members having upturned rear endsand a cross bar connecting the same, frame bars pivotally supported at'the forward ends of the wheel supported frame members, a ground engaging scraper carried by the frame bars, and stop members connected with the frame bars to limit the rocking movement thereof with respect tothe cross bar connecting the u turned rear ends of the wheelsupported frame members. 4,
